Abstract
The present invention relates to a treemap visualization system and method, and more particularly, to a system and method which enables a user to control a visualized three-dimensional treemap with emphasis on a hierarchical structure, without distortion of the sizes of nodes. To this end, the treemap visualization system according to the present invention comprises a raw-data receiving unit, a node-region forming unit, and a node-region protrusion unit. The raw-data receiving unit receives raw data which contains a plurality of hierarchical nodes having weight values. The node-region forming unit forms node regions which are located on a convexly curved surface so as to correspond to the respective nodes. The node-region protrusion unit determines protrusion directions of the respective node regions such that the respective node regions do not overlap with each other, and protrudes the node regions by parallel translating the node regions in the determined protrusion directions.
